Study design:

Case-Control study 

研究目的:

检测脓毒症患者发生急性肾损伤时血液和尿液中相关肾损伤分子(KIM-1、NGAL)及铁死亡标志物(MDA、GSH)、m6A修饰水平及NETs标志物(ELISA)检测结果,探索脓毒症相关急性肾损伤的临床特征。 (1)揭示S100A9通过TLR4和RAGE信号通路在脓毒症肾损伤中的角色;(2)阐明METTL3介导的GPX4 m6A修饰在铁死亡中的调控机制。  

Objectives of Study:

Detecting relevant kidney injury molecules (KIM-1, NGAL) and ferroptosis markers (MDA, GSH), m6A modification levels, and NETs markers (ELISA) in the blood and urine of patients with sepsis to explore the clinical characteristics of sepsis-related acute kidney injury. (1) Reveal the role of S100A9 in sepsis kidney injury through TLR4 and RAGE signaling pathways; (2) Clarify the regulatory mechanism of METTL3-mediated GPX4 m6A modification in ferroptosis.
